I think the reason is the bit-packed format of the string representation in
miniPicoLisp. This makes it quite tedious to scan the bytes for a substring.

Perhaps this is not necessary so much. It is quite straightforward, for example,
to build 'sub?' in Lisp:

   (de sub? (A Str)
      (setq A (chop A))
         (seek '((L) (head A L)) (chop Str))
         Str ) )

No, it might even be an advantage, as it should start up slightly faster. In
reality, the difference is not noticeable though.
